Numbers 4:23-26

23From thirty years old and upward until fifty years old shalt thou number them; all that enter in to perform the service, to do the work in the tabernacle of the congregation.1 24This is the service of the families of the Gershonites, to serve, and for burdens:2 25And they shall bear the curtains of the tabernacle, and the tabernacle of the congregation, its covering, and the covering of the badgers’ skins that is above upon it, and the hanging for the door of the tabernacle of the congregation, 26And the hangings of the court, and the hanging for the door of the gate of the court, which is around the tabernacle and the altar, and their cords, and all the instruments of their service, and all that is made for them: so shall they serve.
